Code 1259
 

This code is VTEC system malfunction. Can anyone tell me what this is. Thanks!

Re: Code 1259
 

The computer did not detect a change in the VTEC oil pressure switch when it tried to activate the VTEC valve.

One common cause is low oil level in the engine.
Several other possible causes too.

first check oil level, make sure its at the full mark on the stick. if it is, next step is dismantle the solenoid and clean the mesh filter screen. if that doesnt work, replace the solenoid. i finally had to replace mine and it fixed the problem. cleaning the screen sometimes works, but might only be temporary.
